Abstract
A scroll-type compressor, while adopting an Oldham mechanism as a rotation prevention mechanism, lubricates an Oldham ring by retaining a medium mixed with oil on a back surface of an orbiting scroll and maintains a compression mechanism in a compact shape. The Oldham ring is provided between the orbiting scroll and a block which supports a drive shaft. An annular thrust race which receives a load in the axial direction from the orbiting scroll is sandwiched between a fixed scroll and the block. An end surface of the circumference of the orbiting scroll is brought into contact with the race, and the race is brought into contact with an end surface of the block to an area outside a pair of key groove portions formed on the block in the radial direction. A retention space, defined by the orbiting scroll, the race, and the block, retains the medium.
